Research Summary

The Pathology Support Group, within the Cellular and Molecular Pathology Branch, provides technical, collaborative and consultative pathology support for NIEHS research programs. For over 25 years, the Pathology Support Group has been a valuable resource for research programs throughout the NIEHS Division of Intramural Research (DIR) and the Division of the National Toxicology Program (DNTP). The Group consists of 4 technical laboratories that are essential components of the DNTP and NIEHS research programs.

Our primary mission is to use the latest technology to function as a centralized core laboratory that provides critical high quality, cost effective and efficient routine and specialized pathology related in-house technical support needed by individual research laboratories across NIEHS and DNTP. In addition to technical support, the group also serves as a consultative and collaborative resource for investigators related to the technical services provided.

The laboratories are staffed by highly experienced, professional, and technical personnel that includes an M.D. pathologist, veterinary toxicologic pathologists, biologists, biological science technicians and on-site contractors.

Ronald Herbert, D.V.M., Ph.D., FIATP leads the Pathology Support Group within the Cellular and Molecular Pathology Branch. He is a veterinary pathologist with over 25 years experience in anatomic and diagnostic toxicologic pathology and pathology peer review of rodent toxicity and carcinogenicity studies. Herbert is a graduate of Tuskegee University where he earned Bachelor of Science degrees in Biology, and Animal and Poultry Science, and a Doctorate of Veterinary Medicine (D.V.M.) from the Tuskegee University School of Veterinary Medicine in 1985. He completed a residency/fellowship and a Ph.D. in anatomic and comparative pathology at the Purdue University School of Veterinary Medicine, graduating in 1991. Subsequently, Herbert completed a 3-year postdoctoral fellowship in toxicologic pathology in the National Toxicology Program (NTP), National Institute of Environmental Health Sciences (NIEHS) and joined as an NTP staff scientist in 1994. He has authored or co-authored numerous peer-reviewed articles in leading biomedical journals as well several book chapters. His areas of interest include chemical-induced toxicity and carcinogenesis, and toxicologic pathology with emphasis in pathology peer review, and pathology of the respiratory and female reproductive systems.
